how do i find the diameter of a circle c=44

  • math -

    excuse me, but what is c?

  • math -

    Oh, if you meant c is circumference, then good. Basically, 2 pi r = circumeference

    so, 2 pi r = 44

    so, pi r = 22

    so r = 22/pi

    that is your answer, roughly 7.

    (that is because pi is roughly 22/7, so 22/(22/7) = 7/22 * 22 = 7. But since pi is not exactly 7, it is a bit off, by about 3 thousandths to be exact)

  • math -

    C = circumference

    C = pi * d
    44 = 3.14 * d
    44/3.14 = d

    14.013 = d

    Whoops Ms. Sue is correct, forgot to multiply by two to find the diameter. What i found was the radius
